Kim Shillinglaw, the BBC’s head of 3D, has admitted that the technology has not taken off with the British public and said that the Corporation will take a three-year break from developing 3D programming at the end of this year.

that would be the end of 2016. By then we'll have a new Avatar sequel and who knows maybe 3-D will continue but more than a pilot (possibly screened in cinemas as an event) for the next Trek series in 3-D sounds unlikely.
